Upsizing from 255/30/19 to 265/30/19 noticeable power loss?

Spun Crankhub · 02-04-2014, 12:50 AM

Recently changed my rear tires from Continental Extreme Contact DW 255/30/19 to a 265/30/19, and swear my car is now slightly less peppy. I mean come on its not a huge width increase.

Going from a 255 to 265 is a very minimal difference. No noticeable power loss should be noticed.

Hmm, I don't think you should notice a power loss from going up in tire width.

Its all in your head

The difference in weight is very small.

I went from 255 to 295 and no loss, all in your head. Might be tire getting better traction and it feels slower because it is not spinning add much.

The grip factor might be doing it. Thanks.
